Of course it is about the vote, or more precisely, the qualification of an individual to have his/her say into his/her government. The broader the voting base and the more in-depth the vote into government, the more democratic the country is perceived. For the West, the voting base is broad and the vote's penetration into government is more than what the average Chinese citizen is allowed. For the US, we have the popular vote for the Presidency. For some European parliamentary system, some PMs are voted by their party members, some are popularly elected. But overall, everyone will judge and be judged based upon inured experience. China is no exception.
Look at the relationship between a government and the citizenry as analogous to that of husband and wife. In any multi-party relationship, and a traditional man-woman marriage does qualify as multi-party because there are two persons involved, there must be a final authority figure, so let us stick with the tradition of that figure being the man (husband) for now. Incidentally, I had a non-American idiot who insists that two does not equal to multi. Freaking moron he was.
Anyway...There is a great difference between contestant policies and contestant ideologies.
To use the marriage analogy, contestant policies is when the husband want steak for every dinner but the wife want chicken and fish for financial and health reasons. Contestant ideologies is when the husband want an 'open marriage' but the wife want absolute fidelity. The latter strikes at the foundation of the relationship.
For the US, contestant ideologies would be democratic vs Marxism. Contestant politics would be Democrat vs Republican. Or in the case of this guy...

Nobody at the national level took Jimmy McMillan seriously. But the bottom line is that in the interests of preserving US multi-party politics, he must be allowed to present himself.
The US does not have contestant ideologies, not because we legally banned any ideology, take note that the Communist Party of the USA is free to conduct its businesses openly, but because we expect any ideology that want to challenge the norm to make its case directly to the people because we believe the people should be the source of our government. So if the CPUSA or The Rent Is Too Damn High Party managed to convince enough voters to send a few to either houses of the Congress, we will see a new arena of contestant politics and may be a change in ideology. But before all of this -- the people must be convinced.
Your China does not even allow contestant politics from the people and whatever contestant policies there are inside the Chinese Communist Party, they are debated behind closed doors among the select few. That is like the husband debating the issues with the voices in his own head and declaring his decision -- dry aged prime rib steak every night -- to be 'democratic'.
So yes, your China
IS a dictatorship.
